The build procedure: a "clean" one - I have a script/make to build a
.deb by untar the src, patch, copy .config, run make oldconfig, run
make, package.

The bisect and config-change procedures were simpler - I was running
"git bisect bad" and make (followed by make modules_install, copy
bzImage to boot, rebuild initramfs) and reboot. For config changes -
drop new config, hand-merged in steps toward the presumed "good" one,
and run make, and install and reboot...

So I was not running explicitly make oldconfig every time, however I
believe that config has been updated to match other options
selected/unselected by make itself (so I have assumed that make
oldconfig has been automagically run sometime during the build).

But for the bisect procedure I did not run "make clean" at every step,
again - in my former bisections it was not needed, and actually saves
a lot of compilation time toward the end of bisection...

As such I could not directly answer your question - however yes -
building "cleanly" from source seems to produce different results than
doing it incrementaly...

Thanks, Woody
